Spark Plugs 101: Everything You Need to Know
The engine in your Nissan vehicle burns fuel and oxygen to produce the power it runs on. However, it can't do that on its own. Its spark plugs start the process -- one aptly called "spark ignition."
How They Work
Turn your key in your vehicle's ignition's lock cylinder, and an ignition switch triggers, activating several ignition parts -- your battery, starter motor, starter solenoid, and ignition coil, for instance. They produce and send an electrical charge, a "spark," to the plugs' leads, which capture it and use it to combust the air and gas inside your engine. This releases power, your engine pistons, crankshaft, and the many other parts that move your vehicle then get going, and so do you. Things stay running, too, thanks to an alternator.
Without spark plugs, though, neither Nissan car nor truck, SUV nor van, could start at all. To make things worse, they can fail eventually. Luckily, there's a set of telltale symptoms to warn you.
Signs They're Going Bad
- Decayed or excessively widening leads
- Weakened electrical conductivity
- Engine misfires and failure
The worst-case scenario: breakage. A broken spark plug can severely damage an engine's cylinders.
How Long They Last Otherwise
Usually, up to 100,000 miles, and for millions of ignitions. Those that aren't made of copper and regular-life are made of platinum or iridium and extended-life. Whichever you end up using, you'll have to replace them all before they reach their recommended mileage limits.
What Your Nissan Vehicle Needs
That depends on the model you're driving, but genuine spark plugs work best either way.
Why Buy Genuine OEM Spark Plugs
Nissan designs them to work with your vehicle specifically. That's not something that every aftermarket brand can necessarily promise.
